Yes! Therefore v2 = 2(KE)/m
= 2(6.00X10-22)/9.11X10-31) = 1.3172X109
v = 3.629X104 m/s

Now using deBroglie's equation:
l = h/mv = 6.63X10-34/(9.11X10-31 X 3.629X104)
= 2.005X10-8 m

Now using Planck's equation:
E = hc/l = 6.63X10-34 X 3X108/2.005X10-8
= 9.92X10-18 J

Now, would you like to see a more elegant and shorter solution?
